Certifacate issue

Được đăng

Starting today whenever I try to open google or other website, i got this error : "You must log in to this network before you can access the Internet. This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate."

when i click Advanced, the following message shows : "www.google.com uses an invalid security certificate. The certificate is not trusted because it is self-signed. Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT" (image attached : image1)

I try this solution : https://support.mozilla.org/en-US/questions/1116116 which is shows something like this (image2)

i try to find program BrowserSafe as the post suggest but there's none. I use windows 7 and this is the first time i experience this problem

Yes, I try to asking them about it but they said no change have been made recently.

Right now (suddenly) I can access the web normally but the problem still persist on wifi network.

Whenever I try to open the login page, it pop another window which said "detectportal.firefox.com/success.txt" but only blank (image attached)
